While we were out and about on Friday, Jonah randomly sang several songs- including the Batman song. A while later while we were in Sam's, we noticed Micah repeating the same thing over and over. We quickly realized he was singing the same song as Jonah. It just didn't sound exactly the same but he was sure trying. I started to video him and he quit. So, Dan sang it once for a reminder. He continued to sing it the rest of the night. OVER AND OVER. I didn't mind though because it was so cute. I laugh every time I see this!
